Finished my build. I am absolutely loving this machine. I'm still tweaking a bit, but still very happy. Tweaking so far includes going with a different bar, the rear sus was a little too compliant for my taste so added the larger token and I think it's good. I want to make the front a little more compliant so will see what's in there for tokens, planning to remove one. I was expecting this build to be good, but I wasn't expecting to love it so much.

strange bushing 25 and 16mm but after a smal search good to find

Can you share links for the bushings? I'm not having any luck finding them.

That wouldn't be UPS's handy work, would it?

Thanks for the replies! Maybe the A22 fits me the way a bike should fit most people but not me?
lower back discomfort isn't something that never happens for me. If I'm active it doesn't bother me but if I'm standing around doing nothing it will.

I am seeing a 10mm increase to stack and a 15mm reduction in reach with the Elves frame.

I've attached a geometry comparison. So the effective top tube is a bit over 19mm with the Elves. The stack #'s says the Elves is 10mm taller but its headtube is 20mm longer and its bottom bracket is 3mm lower compared to the A22, so only a 10mm difference doesn't seem to add up. Maybe its not ~20mm but 10mm has gotta be wrong.

I've had the bike for 2 seasons now but it might only get riden once a week or so. The lower back discomfort slowly builds as the ride goes on. I find I ride with my finger tips on the top of the bars often to get some relief. Afer 60km or so I'm ready to get off the bike. The bar is an integrated and is 44cm wide with a 110mm stem. The top of the saddle is 10cm taller than the tops of the bars.

I'm not sure how relevant it is, but I also attached a pic of my hybrid. This bike gets the most saddle time and I've done many 100km+ rides on it with no discomfort at all. The drop from the saddle to the bars is ~2cm. FWIW the horizontal distance from the center of the seatpost the the center of the bars is 69cm on both bikes.

Thanks again!!

I need 180mm and 160mm 6-bolt rotors. I was going to go with Shimano RT86 rotors but seems the supply of "made in Japan" rotors has dried up for the 180mm and reports of the "made in China" ones are mediocre and take a very long time to bed in. So I'm looking for suggestions. Thoughts?

Anti-seize is better than grease for bolts ?

Technically probably? but unnecessary unless you have a particular issue. It can be a pain to clean up and seems to get everywhere. I use white lithium because it doesn't make a mess and easy to wipe up (and I happened to have it in the drawer).

the non sl is 0,5kg heavier , i think the SL weights more then 1533g,

Yeah that's highly optimistic, and not what I was told. This seems much more realistic.

Yes,we have light weight version for FM138, and the price for frame FM138-SL is $750.
Normal version FM138,size L,weight:2080g±45g.
Light weight version FM138-SL,size L ,weight:1930±45g.
No any strength difference, if the rider weight ≤100KG is ok .

I'm in the process of ordering one, so I can report back when it arrives.

Thanks.

All of this is to get feedback and advice on the build as a whole so context likely maters. I'm pretty new to mountain biking and rode a hardtail I cobled together for the last part of the season to see how I liked it. I f'n loved it!... but also noticed some shortcommings with the bike. Namely suspension, I need rear sus. The hard tail is almost good enough and I don't want to be over biked so going for full sus XC, or downcountry, or light trail?, depending where those blurry lines lay. I'm not working within the limits of a budget but I aim for bang for the buck, or the point of diminishing returns. For example I'm a Shimano XT type person... noticably better than Deore for a cost I feel is justifiable, not thowing 2x the $$$ at it to get XTR just to save a few grams but I can be talked into a lot of things LOL.

I'm a bit into the decision making but still some big ones to make still. I have the suspension, a RS deluxe ultimate 165x45 and a RS SID ultimate 120mm (both take-offs/barely used). I will laikely have to play with shim stacks and try different tunings for the shock but I knew that going in and kinda looking forward to it. I've decided on the Carbonda FM936 (L) to be ordered soon.

One thing I really can't get figured out is wheels. I was going to go for DT 240s but the 350s are much cheaper and the only diference that I can find is ~40g on the wheel set so I'm inclined to go that way. Rims are another thing. I want carbon but the price of the usual suspects seems astronomical. I'm looking at Carbonbeam 30mm internal in AM (325g)... I'm 90kg+ so shouldn't go super light.
